The main task of I/NET is routing the SQL requests to the network. On the server side these requests are received by the daemon proces of Informix Star. Star routs the request to the engine. The engine executes the SQL and the results are send back to the client. From version 6.0 of the Informix Engines the networking software (i.e. Informix Star) are included in the database engine. So no separate installing is requir3ed anymore. Maybe that caused some of the confusion ... Hope this helps Pieter Jordens Holland
